Brown bears and polar bears, can they mate?

[twenty2]

Hello!
Me and my friend are doing some research about the brown bear here in Sweden.
So I was wondering: Is it possible for a swedish brown bear to mate with a polar bear? Or are these two spieces too different from each other?

id assume it was possible as there has been evidence of grizzly bears mating with polar bears creating a hybrid. Here are some showing this hybridization.
