We prove explicit asymptotics for the location of semiclassical scattering resonances in the setting of *h*-dependent delta-function potentials on *\mathbb{R}*. In the cases of two or three delta poles, we are able to show that resonances occur along specific lines of the form *\Im z \sim -\gamma h \log(1/h).* More... Show more
