Abstract:

The nucleus 34 S has been studied up to relatively high spin ( I = 10 ̄ h ) and up to an excitation energy of 16.64 MeV. Data are compared with different shell model calculations where effective interactions involving two main shells, the sd and the fp , are used. For the first time in an N = Z nucleus, it is observed that the promotion of an isoscalar ( T = 0) proton-neutron pair to the fp shell becomes energetically favored at high spin
