抄録	The in plane correlations between alpha particles and various ejectiles were investigated in the reaction of 208 MeV ^<14>N on ^<93>Nb at θ_<HI>=+22°, +50°, and +80°. There were three sources of coincident alpha particles: (i) the sequential alpha decay of the excited ejectiles, (ii) the equilibrium alpha emission from the targetlike fragments, and (iii) the nonequilibrium process. Process (i) contributed mainly to the cross sections with the angular range of θα close to θHI. Process (ii) contributed to the lowest part of the alpha energy spectra irrespectively of θ_<HI> and θ_α. The remaining part was ascribed to process (iii). For this process the differential coincidence cross section of the lower energy part of the alpha particles was approximately factorized as d^4σ/dΩ_<HI>dΩ_αdE_<HI>dE_α=K(d^2σ/dΩ_<HI>dE_<HI>)_<singles>(d^2σ/dΩ_αdE_α)_<singles> with K∼0.4/b, whereas the higher energy part of the alpha particles emitted at the forward angles had a tendency to coincide weakly with the ejectiles emitted at the backward angles (θ_<HI>=+50° and +80°) as compared to the lower energy part of the alpha particles.NUCLEAR REACTIONS ^<93>Nb(^<14>N, HIα), E=208 MeV, θ_<HI>=22°, 50°, 80°; measured two-dimensional H—α coincident energy and angular correlations; deduced reaction mechanisms.

DCTERMS.abstract	The in plane correlations between alpha particles and various ejectiles were investigated in the reaction of 208 MeV ^<14>N on ^<93>Nb at θ_<HI>=+22°, +50°, and +80°. There were three sources of coincident alpha particles: (i) the sequential alpha decay of the excited ejectiles, (ii) the equilibrium alpha emission from the targetlike fragments, and (iii) the nonequilibrium process. Process (i) contributed mainly to the cross sections with the angular range of θα close to θHI. Process (ii) contributed to the lowest part of the alpha energy spectra irrespectively of θ_<HI> and θ_α. The remaining part was ascribed to process (iii). For this process the differential coincidence cross section of the lower energy part of the alpha particles was approximately factorized as d^4σ/dΩ_<HI>dΩ_αdE_<HI>dE_α=K(d^2σ/dΩ_<HI>dE_<HI>)_<singles>(d^2σ/dΩ_αdE_α)_<singles> with K∼0.4/b, whereas the higher energy part of the alpha particles emitted at the forward angles had a tendency to coincide weakly with the ejectiles emitted at the backward angles (θ_<HI>=+50° and +80°) as compared to the lower energy part of the alpha particles.NUCLEAR REACTIONS ^<93>Nb(^<14>N, HIα), E=208 MeV, θ_<HI>=22°, 50°, 80°; measured two-dimensional H—α coincident energy and angular correlations; deduced reaction mechanisms.
