The {beta}{sup +}/EC half-lives of medium heavy N{approx}Z nuclei with mass number A{approx}64-80 are calculated within the deformed shell model (DSM) based on Hartree-Fock states by employing a modified Kuo interaction in ({sup 2}p{sub 3/2},{sup 1}f{sub 5/2},{sup 2}p{sub 1/2},{sup 1}g{sub 9/2}) space. The DSM model has been quite successful in predicting many spectroscopic properties of N{approx}Z medium heavy nuclei with A{approx}64-80. The calculated {beta}{sup +}/EC half-lives, for prolate and oblate shapes, compare well with the predictions of the calculations with Skyrme force by Sarriguren et al. Going further, following recent searches, half-lives for 2{nu} {beta}{sup +}{beta}{sup +}/{beta}{sup +}EC/ECEC decay for the nucleus {sup 78}Kr are calculated using DSM and the results compare well with QRPA predictions.
