Starting from a Skyrme interaction with tensor terms, the β-decay rates of ^{52;54;56;58;60}Ca have been studied within a microscopic model including the 2p − 2h configuration effects. It is shown that a redistribution of the Gamow-Teller strength due to the 2p − 2h fragmentation is mostly sensitive to the multi-neutron emission probability.
