Muon capture reaction (μ-,nu/sub μ/) with nuclei

A pulsed source fo stopped μ- and experimental muon facility associated with the Pulsed Storage Ring (PSR) under construction at LAMPF is a distinct possibility. With a new superconducting solonoid muon channel, one could expect negative muon fluxes at the PSR to match or exceed those at the present LAMPF Stopped Muon Channel (SMC). The time structure of the beam opens a whole new range of experimental possibilities in nuclear muon capture. With LAMPF II, the μ- flux could exceed that at SMC by up to two orders of magnitude. With the possibilities of these greatly improved and more versatile μ- beams, it seems appropriate to reexamine the subject of muon capture on nuclei. The purpose of this contribution is to give an overview response to the question what can be learned from the muon capture reaction (μ-,nu/sub μ/) on nuclei
