1 Isospin Mixing And In-beam Study Of 56 Co Non-yrast States At MLL/Miniball. Motivation And First Glance On The Results Of The Experiment Ana Montaner Pizá. Instituto de Física Corpuscular IFIC, Valencia, Spain. MINIBALL Workshop. 24-25 October 2013. CERN, Geneva.

2 Physics motivations  Starting point: Comparison of beta decay of 56 Zn with its mirror process 56 Fe( 3 He,t) 56 Co. Motivations: 1. Study of the γ de-excitation of the IAS in 56 Co. 2. Clarification of the J π assignment of two key levels in 56 Co. At RCNP (Osaka, Japan) At GANIL (France) 1

3 56 Co present knowledge  Present status of the 56 Co nucleus from ENSDF Evaluated Nuclear Structure Data FileENSDF Evaluated Nuclear Structure Data File 3076.0 keV, 1 + ? 2635.9 keV, 1 + ? Isospin mixed states 2

4 Studying the mirror process: Beta decay experiment at GANIL  The beta decay experiment was carried out at GANIL in 2010, focused on the production of 56 Zn. (S. Orrigo, B. Rubio, Y. Fujita, W. Gelletly et. al.)  The analysis of this experiment is very advanced. In order to fully interpret this work a better understanding of the 56 Co excited states will be crucial. 56 Zn → 56 Cu + β + 56 Z n 4 EXOGAM clovers for gamma detection 4 EXOGAM clovers for gamma detection 4 EXOGAM clovers for gamma detection 3

5 Motivation I: Study of the γ de-excitation of the IAS in 56 Co Isospin mixed states Reference: S.E.A. Orrigo et al., INPC 2013 Proceedings, EPJ Web of Conferences (2013). 4 Very low S p Proton decay for the IAS is isospin forbidden  gamma de-excitation is possible. IAS

6 Motivation II: Clarification of the J π assignment of two key levels in 56 Co (1) Reference: "Isospin mixing for the isobaric analog state studied in a high-resolution 56 Fe(3He,t) 56 Co reaction". H. Fujita, Y. Fujita et al., submitted to PRC. 5

7 Motivation II: Clarification of the J π assignment of two levels in 56 Co (2) Well known 1 + distribution 3.076 MeV 2.633 MeV 2 + distribution Reference: "Isospin mixing for the isobaric analog state studied in a high-resolution 56 Fe(3He,t) 56 Co reaction". H. Fujita, Y. Fujita et al., submitted to PRC. 6

8 MINIBALL experiment at the MLL (Munich)  Experiment carried out in the Maier-Leibnitz-Laboratorium (MLL) at the Technische Universität München (TUM), in June 2013.  Reaction: 56 Fe(p,n) 56 Co  56 Fe Target thicknesses: 1 and 2 mg/cm 2  Proton beam: 10 MeV and 12 MeV  Beam intensity: 1-3 nA  Duration: 6 day  Angle calibration reaction: 32 S(d,p) 33 S in inverse kinematics. 7

10 Preliminary results of MINIBALL experiment at MLL 962 keV 891 keV ? 962 891 869 796 18781806 Isospin mixed states T=1 0 + T=2 0 + IAS Either not there or much weaker, and we will get upper limits in due time 1185  Study of the γ de-excitation of the IAS in 56 Co. Gated in the 1185 keV line 9

11 Preliminary results of MINIBALL experiment at MLL (2) 1185 keV peak from the de-excitation of the 2635 keV level: # Counts: 1.12·10 5 # Counts per measurable angle: 1.12·10 5 /(4x3x6) ≈ 1555  Clarification of the J π of the levels 3076 keV and 2636 keV in 56 Co using angular correlations. 1185 keV peak 962 891 869 796 18781806 Isospin mixed states T=1 0 + T=2 0 + IAS 1185 2635.9 keV 480 Miniball: 4 clusters 3 crystal/cluster 6 segments/crystal Gated in the 480 keV line 10

12 Conclusions  Stability and well behaviour of MINIBALL detectors.  Crosstalk problem.  We have to restrict to coincidences between different Clusters.  From the motivation point of view:  Angular correlations: we will be able to clarify the spin-assignment of the 2636 keV and 3076 keV states.  Gamma de-excitation of the two 0 + isospin mixed states  We should be able to set meaningful upper limits to those "new" two gamma lines from the de- excitation of the 0 + T=1 state. 11
